Your second reference (nm) refers to the wavelength, or frequency (color) of the energy. The Ultraviolet (UV) Index, developed in 1994 by the National Weather Service (NWS) and the US Environmental Protection Agency (EPA), helps Americans plan outdoor activities to avoid overexposure to UV radiation and thereby lower their risk of adverse health effects. RADIS is a fast line-by-line code for high resolution infrared molecular spectra (emission / absorption, equilibrium / nonequilibrium). For reference, the wavelength of ultraviolet light is in the range 100-400 nm, visible light is in the range 400-800 nm, and infrared light is in the range of 800 nm - 10 microns and beyond. RADIS has powerful tools to post-process spectra created by the line-by-line module or by other spectral codes. ; apply instrumental slit functions. The amount of UVAB light intensity is displayed in mW/CM2 (how much energy is concentrated per square cm of area). Milliwatt (SI symbol: mW) is a unit for measuring electrical power, equal to one-thousandth (10^-3) of a watt. Radio EMC standards may reference radiated RF power limits for ERP or EIRP in terms of dBm or mW. As other members have indicated, your meter will monitor a specific portion of the "energy spectrum" - google that for an eye … ; rescale a spectrum without redoing the line-by-line calculation.
